Usually athletes are the ones earning adoration from fans, but thanks to Hughes' antics in the stands, Federer (and his charity doubles partner Bill Gates) smiled courtside in Seattle on Saturday at the fourth edition of The Match for Africa.

An epic time in Seattle! The crowd was Electric. The Support for the Roger Federer Foundation was Unbelievable. https://t.co/jL29hehZ2g
